10/12/2023 0 Comments Casa diablo iv geothermal project![]() Four production wells and two injection wells were completed in December, 1983. Construction of the plant started in August of 1983 with completion planned on August 1, 1984. A contract for the sale of the electricity has been executed with the Southern California Edison Company. Contracts for the lease of the land and the use of the Magmamax process have been executed with Magma Energy, Inc. The present status of the project is as follows. The authors have been involved for 10 years in the development of this resource located on 90 acres of fee land owned by Magma Energy, Inc., who drilled and tested 8 wells in the early 60's establishing the existence of a low salinity (1500 ppm) moderate temperature (330 F) resource at shallow depths (400' - 700').

Howle, J.F., Evans, W.C., Galloway, D.L., Hsieh, P.A., Hurwitz, S., Smith, G.A., and Nawikas, J., 2019, Hydraulic, geochemical, and thermal monitoring of an aquifer system in the vicinity of Mammoth Lakes, Mono County, California, 2015–17: U.S. Groundwater-chemistry data from three wells indicated that shallow groundwater naturally mixes with a small component of geothermal water along the northern periphery of the shallow aquifer system at Mammoth Lakes. The digitally filtered water-level data indicated that some hydraulic communication exists between the deep geothermal aquifer and shallow groundwater aquifer at the location of the flow test, northeast of Mammoth Lakes. ![]() These are further considered in a companion evaluation of potential physical and chemical influences on the water-level data collected during the flow test. Additionally, the methodology used to develop digital (mathematical) filters to remove or reduce the effects of barometric pressure and solid Earth tides on the continuous water-level records is discussed.ĭigitally filtered water levels for a 2017 flow test of a deep geothermal production well are described, and various aquifer responses observed during the flow test are discussed. Also discussed are the methods of water-sample collection and characterizations of the water chemistry in numerous wells in the multilayered aquifer system beneath Mammoth Lakes. ![]() The methods of data collection for continuous water levels and quarterly water-temperature profiles for two 600-foot-deep monitoring wells during 2016 through 2017 are discussed. The publicly available data and the analyses provided here represent quality-assured and peer-reviewed information to help with the management of the thermal and non-thermal water resources beneath and in the vicinity of the town of Mammoth Lakes, California. Geological Survey has been working in cooperation with the Bureau of Land Management, Mono County, Ormat Technologies, Inc., and the Mammoth Community Water District to design and implement a groundwater-monitoring program for the proposed Casa Diablo IV Geothermal Power Project in Long Valley Caldera, California, to characterize baseline groundwater-level, water-temperature, and water-chemistry conditions at dedicated monitoring wells and municipal supply wells.
